AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

[T]he occurrence of drill marks [has been 

found] at the lower ring region of the rear 

pressure bulkhead between [the] 

circumferential splice joint and rear skin 

located between stringers 12 and 13. These 

marks may result in formation of fatigue 

cracks accelerated by corrosion reducing the 

structural strength of the rear pressure 

bulkhead, which may cause a sudden 

decompression of the passenger cabin. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

15, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 15, 2011. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on February 10, 2011 (76 FR 

7511). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

[T]he occurrence of drill marks [has been 

found] at the lower ring region of the rear 

pressure bulkhead between [the] 

circumferential splice joint and rear skin 

located between stringers 12 and 13. These 

marks may result in formation of fatigue 

cracks accelerated by corrosion reducing the 

structural strength of the rear pressure 

bulkhead, which may cause a sudden 

decompression of the passenger cabin. 

* * * * * 

The required actions include doing a 

detailed inspection for signs of drill 

marks and repairing if necessary. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 


srobinson on DSKHWCL6B1PROD with RULES
27238 Federal Register / Vol. 76, No. 91 / Wednesday, May 11, 2011 / Rules and Regulations 

Costs of Compliance 

We estimate that this AD will affect 

241 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this AD to the U.S. operators to 

be $20,485, or $85 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 2 work-hours and require parts 

costing $20, for a cost of $190 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this AD: 

1. Is not a ’’significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ’’significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt.

Subject 

(d) Air Transport Association (ATA) of 

America Code 53: Fuselage. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

[T]he occurrence of drill marks [has been 

found] at the lower ring region of the rear 

pressure bulkhead between [the] 

circumferential splice joint and rear skin 

located between stringers 12 and 13. These 

marks may result in formation of fatigue 

cracks accelerated by corrosion reducing the 

structural strength of the rear pressure 

bulkhead, which may cause a sudden 

decompression of the passenger cabin. 

* * * * * 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) Before the accumulation of 20,000 flight 

cycles, do a detailed inspection for signs of 

drill marks at the left and right lower ring 

region of the rear pressure bulkhead between 

the circumferential splice joint and rear skin 

between stringers 12 and 13, in accordance 

with EMBRAER Service Bulletin 170–53– 

0082 or 190–53–0042, both Revision 01, both 

dated April 28, 2010, as applicable. If drill 

marks are found, repair before further flight, 

in accordance with EMBRAER Service 

Bulletin 170–53–0082 or 190–53–0042, both 

Revision 01, both dated April 28, 2010, as 

applicable. 

Note 1: For the purposes of this AD, a 

detailed inspection is: ‘‘An intensive 

examination of a specific item, installation, 

or assembly to detect damage, failure, or 

irregularity. Available lighting is normally 

supplemented with a direct source of good 

lighting at an intensity deemed appropriate. 

Inspection aids such as mirror, magnifying 

lenses, etc., may be necessary. Surface 

cleaning and elaborate procedures may be 

required.’’ 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

Although EMBRAER Service Bulletins 

170–53–0082 and 190–53–0042, both 

Revision 01, both dated April 28, 2010, 

specify doing a general visual inspection, this 

AD requires doing a detailed inspection.
